Abstract (en)

[origin: WO9857893A1] A method for the remediation of arsenic is presented, comprising providing an aqueous solution of inorganic arsenic species, and passing the solution of inorganic arsenic species over a substrate comprising a zero valent metal under anaerobic conditions, thereby reducing the arsenic species and forming arsenic-metal coprecipitates. Preferably, the metal is iron in the form of iron filings, and a source of sulfate ions is also present, resulting in the precipitation of arseno-pyrites.
